Title: Method of and apparatus for the manufacture of hollow articles from thermoplastic material
IPC: B29C51/02
Filed: 1965-11-18
Abstract: A method of moulding a hollow article comprises the steps of depositing a molten slug of thermoplastic material, e.g. PVC, into a heated die, compressing the slug into a flat preform and subsequently deep drawing or vacuum forming said preform to the final shape whilst it is still held in said die. In one embodiment (see the Figure) a slug from a withdrawable extrusion head 1 is deposited into a die 2 and is compressed into a preform by a plunger 3. The bottom 4 of the die is then lowered, the preform being retained in its position, and vacuum applied to the space below the preform to suck it into contact with the lowered bottom to form the finished article. In a second embodiment (see Figs. 2 and 3, not shown) a slug (13) is deposited into one of several dies mounted upon a rotating table (8) and the table indexed to a station at which a preform is formed by a plunger (12). A second rotating table (9) carrying vacuum moulds (14) is partially superimposed above table (8) so that the preform may be indexed under a mould (14) carried by the table 9 and vacuum formed therein. The article is retained by the mould and the table (9) indexed to bring the mould to an ejection station where the finished article is removed.

Title: Method of coating paper
IPC: B05D1/26
Filed: 1967-07-20
Abstract: A continuous process for coating a web of dielectric material with a plastics material comprises directing the web and an extruded film of the material along paths which converge, and subjecting the film in the region of convergence to the action of an electric field to force the film into bonding contact with the web, the region of the electric field being of a lesser width than that of the web. As shown, in the region between rolls 30 and 32, the web 20 contacts the rounded edge of a bar 31. The length of the bar 31 is less than the width of the web, thus restricting the electric field to a central region of the web, bonding taking place in this central region only. An electrode structure 37 produces the electric field in this region to bond the extruded film 36 to the web. The bar 31 may be electrically grounded or connected to a positive or negative potential source. The web may be of paper. The film may be of any of the polymers and copolymers of propylene, ethylene and butylene or of polystyrene. The lateral edges of the laminate, to which edges the film will not have been bonded, may be trimmed.

Title: A process for melt spinning hollow filaments and spinnerets for use therewith
IPC: B29C48/09
Filed: 1968-08-17
Abstract: Hollow filaments of synthetic organic thermoplastic polymeric material are produced by melt spinning the material through a spinneret under such conditions that the " die swell factor " of the material is between 2À5 and 10, the spinneret being provided with at least one unobstructed extrusion orifice which defines, without completely surrounding, an area of the spinneret face devoid of orifices, or being provided with two or more unobstructed extrusion orifices which define, without completely surrounding, an area of the spinneret face devoid of orifices. The minimum distance between the adjacent ends or terminal portions of the circumscribing orifice or orifices is between 3 and 15 mils. (0À076 and 0À38 mm.). The molten polymeric material may be extruded through the spinneret under such conditions that the " die swell factor " of the material is between 2À5 and 10, and the average diameter, D 2 of the imperforate area of the spinneret being greater than AD 1 , wherein A is the die swell factor of the polymeric material and D 1 is the maximum orifice width in a direction radial to the centre of the imperforate area. The imperforate area may be defined by at least two separate and distinct orifices having " shape factors " greater than 1À4. D 2 may be greater then 2 AD 1 . The expression " die swell factor " is defined as the ratio of the maximum diameter of the stream of extruded polymer melt to the diameter of the orifice opening when employing a spinneret having a circular orifice sufficiently remote from any other orifices of the spinneret that the stream does not coalesce with the stream or streams extruded from any other orifice or orifices which may be present in the spinneret. The expression " shape factor " is defined as the ratio of the longest straight line which can be drawn within a cross-section of the orifice to D 1 . The molten polymeric material used may comprise a dispersion of a first polymer as a distinct discontinuous phase within a continuous phase of a second polymer. The first polymer may be a polyester such as a polyethylene terephthalate and the second polymer may be a fibre-forming polyamide such as a polycaproamide. Filaments made using these polymer dispersions may consist of a sheath containing an internal longitudinally extending cavity, the sheath comprising a continuous phase polymer containing dispersed therein a second polymer phase in the form of microfibres lying predominantly parallel with the axis of the filament. The microfibres may have a length-to-diameter ratio greater than 5. The portion of the spinneret face comprising an area devoid of orifices and defined by a single circumscribing orifice may be as shown in Fig. 9 and examples of portions of spinneret faces comprising an area devoid of orifices and defined by an arrangement of two or more orifices are shown in Figs. 2 to 8 and 13.

Patent ES-362193-A1 (ES)
Title: Battery charging systems
IPC: H02J7/00
Filed: 1968-12-17
Abstract: A system for charging a battery from a D.C. source comprises an ON/OFF switching device, the ON period of which is determined by either the voltage of the source or of the battery and the OFF period of which is determined by the voltage of the battery or of the source respectively. A battery B is arranged to be charged from a D.C. source S by way of a serially connected transistor TR1 and an inductor L1. Transistors TR2, TR6 form a normal multivibrator circuit with a transistor TR4 forming a cathode follower to increase the amplification of transistor TR6. The multivibrator operates such that a winding N1 of a transformer T1 is energized when transistor TR6 is conductive. A winding N3 of the transformer T1 then biases transistor TR1 into conduction, whereby the battery B receives charging current from the source S. With the multivibrator in its alternative state with transistor TR2 conductive, the transformer T1 is de-energized and transistor TR1 non-conductive. The energy in the inductor L1 then produces a current which continues to charge the battery B but at a level lower than when the transistor TR1 is on. The ON time for the transistor TR6 and hence of the transistor TR1 is determined by the components D3, C1, R7, R8 and the voltage between the lines 11, 12, that is, the voltage of the charging source S. The ON time of the transistor TR2 and hence the OFF time of the transistor TR1 is determined by the components C2, R11, R12 and the effective impedance of a transistor TR3 which is responsive to the voltage of the lines 11, 13 that is, the voltage of the battery B by virtue of the connection between the base of the transistor TR3 and potentiometer RV2. Alternatively, the circuit may be arranged so that the ON time depends on the battery voltage and the OFF time on the charging source voltage. In both alternatives the ON time is inversely dependent upon the voltage and the OFF time directly dependent upon the voltage concerned. A winding N2 on the transformer T 1 ensures the reset to zero of the flux in the transformer when transistor TR1 is OFF and transistor TR5, diode D4, resistor R9 and zener diode D2 are provided for protective purposes. The resistor R9 may be temperature responsive with an opposite characteristic to that of transistor TR5.

Title: Thread supply apparatus for textile machinery
IPC: B65H51/22
Filed: 1971-01-27
Abstract: and DIE. A thread supply device for a shuttleless loom or knitting machine comprises a stationary helically grooved cylinder 2 and a rotatable two pronged fork 6-8 which winds thread, supplied via eye 17, onto the cylinder. Yarn is removed via an eye 18 adjustable relative to the cylinder. The device functions as a positive feed with yarn passing through guide in position 18', preferably however the guide 18 is positioned axially of the device which functions as a store. In a variant the eye is adjustable vertically of the cylinder. Accumulating turns of thread move down the thread but are frictionally retarded where they pass over the prongs. The resultant axial movement of the prongs and axle 12 against spring 9 disengages clutch 11, 13 in its drive. The fork may be driven by an individual motor housed in the cylinder, whose speed may be controlled by a yarn tension sensor pivoted at the end of guide arm 55. The forks of several devices in a machine may be driven by toothed belt engaging a pinion attached to shaft 12. One fork may be driven from another by gearing. The revolutions of the fork may be counted by a periodically closed switch, or photoelectric or magnetic sensing. In further embodiments (Figs. 14, 15 and 17) the grooved cylinder is constituted by a straight cylinder wrapped by a helical coil. The yarn is wound for positive feed by inclined prongs mounted in a body above the cylinder. The inlet and outlet eyes are adjustable alongside the cylinder in unison. In a similar arrangement (Fig. 15) for yarn storage the spacing of the prongs is adjustable.

Title: Bi-processor data handling system including automatic control of exchanges with external equipment and automatically activated maintenance operation
IPC: G06F11/16
Filed: 1973-04-24
Abstract: Two microprogrammed processors of identical hardware and software facilities are synchronously operated for exchange operations with a plurality of external store and peripheral units. The exchange connections from the processors to the external units pass through gate circuits one of which only is operative at a time. Each processor has an output at which all processed words, whether instructions, microinstructions, operands or results are successively available. Comparator means permanently compare such words from the two processors and, when a mismatch occurs, block the gate circuits and their own comparison outputs and control execution in both processors of a failure detection and check up routine. Each processor includes exchange control claiming and exchange control disclaiming outputs. When a processor activates its exchange control disclaiming output, its gate means are blocked, the output of the comparator means is inhibited and the other processor is automatically qualified to proceed with the exchanges. Casually, the processors are then desynchronized.
